Party walls and boundaries
A box tells you to ask your legal adviser about the boundary. Has the surveyor drawn where the legal boundary lies?
No. The surveyor has not drawn where the legal boundary lies. The box tells you to ask your legal adviser, which is a referral, not a plan of the legal line. The visit can note fences, walls and hedges it could see. Those physical features are not the boundary on the title. The survey has not mapped ownership and has not decided the line. The question in the box belongs with the solicitor and the title plan.

What is the fuller explanation?
A legal boundary is a title question. It may follow a wall, sit offset from a fence, or be unclear on the ground. Party wall legislation is about certain work near a boundary, not a drawing that awards the garden. The surveyor uses a box so a legal point is not left looking like a condition rating of the fence. The mechanism is a signpost. It is not fieldwork with pegs, and it is not a concluded boundary agreement.
Ask the solicitor to compare the title plan with what is on the ground, and to raise the boundary with the seller if the plan and the fence do not match. Do not ask the surveyor to ink a legal line the inspection did not establish. A lender may want the boundary clear on paper. The report has already sent you to the legal adviser. Follow that, and keep the survey's description of the fence as description only.
What should you ask your surveyor?
- Which physical feature did the survey actually see along this line?
- Does the title plan agree with that feature?
- Is the box a referral rather than a decided boundary?
What are the typical next steps?
- Ask the solicitor to read the title plan against the ground.
- Treat the survey box as a prompt, not as a drawn legal line.
- Do not tell the lender the surveyor has fixed the boundary.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
Does the Party Wall etc. Act draw who owns the garden?
No. Party wall law is about notifiable work and procedures between neighbours. It is not a map of ownership and it is not what the survey drew. The box sends the boundary question to your legal adviser. The survey has not decided where the legal line lies and has not served any party wall notice.
Does the fence on the ground settle the title line?
No. A fence is a physical feature. The title line is in the deeds and the plan, which may not sit on the fence. The survey can describe the fence and still tell you to ask the legal adviser, which is what the box does. Ownership is not settled by boards, posts or a neat hedge seen on the day.
